- •
A pyrene derivative-SDS assemblies-Cu2+ based ternary sensor system was built.
- •
The ternary system is highly sensitive to arginine and lysine in aqueous solution.
- •
The sensor shows the lowest detection limits of Arg (5.2 nM) and Lys (14.6 nM).
- •
The sensor displays dual responsive signals of “excimer-off” and “monomer-on”.
- •
Two different mechanisms occur to sensing different concentrated amino acids.
